It is the final type of problems which we'll be looking at in this section. We are going to be looking at mixing solutions of distinct percentages to obtain a new percentage. The solution will contain a secondary liquid mixed with water. The secondary liquid may be alcohol or acid for instance.
The standard equation which we'll employ here will be the following.
Notice as well that the percentage have to be a decimal. Thus if we have an 80% solution we will have to use 0.80.
y+11=(y+10)+(y-7)
6x960=k
Example Evaluate each of the following logarithms. (a) log1000 (b) log 1/100 (c) ln1/e (d) ln √e (e) log 34 34 (f) log 8 1 Solution In order to do
solve log(5*8)
